FIELD OF THE INVENTION

The described invention relates to an ambidextrous working glove havingfish scale-textured inner and outer surfaces and methods of making same.

BACKGROUND

Typical uses of working gloves include food processing, chemicalhandling, pesticide spraying, and the like. The thickness of workinggloves should not hamper tactile sensation. However, the working glovesshould be strong enough to resist rupture. It is desirable in workinggloves to provide roughened or textured inner and outer surfaces, sinceworking gloves with smooth surfaces make gripping items difficult for awearer. A textured outer surface enables a wearer to adequately gripitems that may be slippery. In addition, the inner surface of the gloveis in close contact with the wearer's skin and does not absorb thewearer's perspiration. A textured inner surface may reduce thelikelihood of slippage of the wearer's hand inside the working gloveduring use that may be caused by perspiration, wherein the texturedinner surface may enable the perspiration to flow away from anypressured surface without “skating” of the glove over the surface of thewearer's hand.

Current attempts to form a glove with textured inner and outer surfaceshave employed methods whereby a texture is imparted to the inner surfaceby using a textured form, and either treating the film forming the glovein a manner that erodes the film thereby creating texture on the outersurface, or by spraying particles onto the outer surface of the glove.Such methods are unsatisfactory, due to various factors, such as, forexample, lack of dexterity, difficulty in donning, non-uniform thicknessof the glove causing the glove to rupture during use.

Current working gloves frequently utilize donning powders, such as, forexample, cornstarch or talc, to enable a wearer to don the glove moreeasily. However, donning powders can contaminate wounds, irritate skin,leave a residue on equipment and clothing, and mechanically interferewith some procedures that a user may perform while wearing the workingglove.

Previous attempts to ameliorate the slippage of the glove caused by thewearer's perspiration have proved unsuccessful. For example, cottonflock linings frequently are only able to absorb small amount ofperspiration before losing their effectiveness.

Additionally, present methods to impart a contact-reducing texture tothe inner surface of the glove to ameliorate the effects of the wearer'sperspiration and/or aid donning frequently reduce mechanical performanceof the glove, leading to rupture of the glove.

Accordingly, there remains a need for a working glove with texturedinner and outer surfaces, with improved dexterity, ease of donning and areduced frequency of failure during use.
